Hi guys. That's a stupid question but...ATM what's the best PC considered the power of the CPU and the $ cost for it?

I'm using an old Pentium (quad core 2.66) and celeron (dual core 3.2) right now but in the fastest CPU list of PrimeGrid they are very weak.

Can u suggest me the best (economic) CPU for my next rig?

I reckon check out these options:
AMD Ryzen 7 3800X 8-Core Processor (or 3700X may be better)
AMD Ryzen 9 3900X 12-Core Processor
AMD Ryzen 9 3950X 16-Core Processor
AMD chips are divided into chiplets or CCXs - when crunching, it is much better to contain your multi-threading within a CCX. I don't know about CCX for the first option, but as far as I know, the 12 core has 2 x 6 core and the 16 core has 2 x 8 core. The 2 x 8 core may give you more options of crunching with LLR tasks of larger sizes - 1,2,4 or 8 cores for multi-threading.
Intel chips don't have CCXs - but use more power and are more expensive - and unless you want to go for the really expensive 9xxx-X or 109xxx-X chips with dual AVX512, core for core at similar clock speeds have about the same crunching potential.

It also depends on the Project you want to do most of your cpu crunching for, Prime Grid favors, up until the newer expensive AMD cpu'swith "chiplets", Intel brand cpu's. So unless you are going to get a newer AMD cpu and you want to stay here at Prime Grid than Intel is the way to go. As far as which Intel cpu is best of course the newest ones are better than the older ones, but that's not exactly what you asked.

If you are going to go Intel I would go I7 something depending on your budget and then figure out which motherboard and ram combination you want. For Prime Grid faster ram IS better than slower ram and yes you can run out of memory depending on what project you are running and what else is running on your pc. I'm running the ESP-LLR tasks on an older I7-3930K that is using 110MB of ram for each task and takes around 6 hours for each one using all 6 real cpu cores. It has 12GB of ram and is doing fine and other than a couple of nci workunits it doesn't do anything else, Windows Task Manager says it has about 9.5GB or ram available.

My answer primarily covers LLR work, since that covers most CPU projects here.

The most logical choice would probably be one of the AMD Zen 2 CPUs. It is not easy to give a specific value answer because that will depend on what else you put around the system. Zen 2 desktop CPUs from Ryzen 3500 and up, including Threadrippers are all great. At least the last time I looked, the pricing "per core" scaled pretty well up the model range. So you can pick a point to suit your budget.

Some points to watch out for, one is don't cheap out on the motherboard. For this type of work you need decent power delivery otherwise stability can be a problem. Also you will need a good cooler as they run hot, more due to power density and absolute power. Do not rely on the one they include. Also some consideration needs to be given. For most LLR work unit types at Primegrid you want to arrange them to fit in each CCX so memory doesn't become the limit.

The other choice is to look at Intel recent HEDT options. Since Skylake-X, these have included AVX-512 which can do up to double the work (per core, per clock) compared to AVX2. The list pricing of latest Cascade Lake-X is competitive vs AMD per-core, although stock seems to be a problem. You might also see older generations on offer here and there too. These can be power thirsty, but they really chew through the work if you can feed them well. Because their caches aren't as generous, you really need to get the best ram you can to go with it.

Regular Intel desktop CPUs are also ok, but they still command some price premium over AMD so they will rarely be the "value" choice.

I have a question: do 9900X and 10900X generally offer the same performance if overclocked to 4.8GHz both?

Could the default cooler (Wraith Spire) settle 3700X? I'm about to buy it in the summer (or winter for southern hemisphere).

The list pricing of latest Cascade Lake-X is competitive vs AMD per-core, although stock seems to be a problem. You might also see older generations on offer here and there too. These can be power thirsty, but they really chew through the work if you can feed them well. Because their caches aren't as generous, you really need to get the best ram you can to go with it.

If considering Intel 99xx-X or 109xx-X (I think I've typed that correctly this time), you really want to go for the 16 or 18 core variants. The 16 core X has 2.75 Mb more L3 cache than any of 10 to 14 core variants. The 18 core X has 2.75 Mb more L3 cache than the 16 core variant. Each X CPU has 1 Mb L2 cache per core.

When allocating CPU resources to CPU LLR tasks, you will want to leave at least a core free to service the GPU. If you are running 2 multi-threaded CPU tasks, you will need to leave 2 cores free for the GPU.

To run LLR tasks most effectively, you want to run them within the cache and not relying on RAM which is slower.

The LLR tasks take up cache, equal to 8 x FFT size of LLR task.
You can find FFT size in "Task Details"
Example http://www.primegrid.com/result.php?resultid=1093096417

For X CPUs, the amount of available cache is L2 + L3 . This is different to the previously recommended AMD CPUs and regular desktop Intel CPUs which is L3 cache only - which isn't an issue for the AMD CPUs as they have a lot of L3 cache.

It is probably easier to give an example:
PSP LLR can have an FFT size of 2.048 Mb - it has been a while since I ran PSP so I am using info from an old table of FFT sizes.
https://www.primegrid.com/forum_thread.php?id=8682&nowrap=true#130940

Cache needed to run 2 tasks is 2 x 8 x 2.048 Mb = 32.768 Mb
Leaving 2 cores for the GPU, the L2 + L3 cache needs to be at least 34.768 Mb
A 14 core 9940X or 10940X has 14 Mb L2 cache and 19.25 Mb L3 cache which isn't enough.
A 16 core 9960X has 16 Mb L2 cache and 22 Mb L3 cache which is enough.
The 18 core 9980XE or 10980XE has 18 Mb L2 cache and 24.75 Mb L3 cache which is even better for versatility of running different combinations of LLR tasks.

How I use my 9980XE:
1 x SOB task at a time with core(s) free for the GPU. Last time I ran SOB, it was 14-core tasks with times of 36,000 sec which I understand to be blisteringly fast.
2 x PSP, or 2 x CUL, or 2 x WOO, or 2 x GCW (8-core tasks) at a time with 2 cores free for the GPU
4 x 321 (4-core tasks) at a time with 2 cores free for the GPU

For my 9960X:
The same as above except it was 2 cores less for SOB tasks, 1 core less for each of PSP, CUL, WOO and GCW tasks (and 2 cores for GPU)
And 5 x 321 (3-core tasks) with 1 core free for GPU.

I have probably made this a bit too complicated.

I have a question: do 9900X and 10900X generally offer the same performance if overclocked to 4.8GHz both?

In theory yes. Note in reality, you're not going to run them at 4.8 GHz if you use AVX-512.

Could the default cooler (Wraith Spire) settle 3700X? I'm about to buy it in the summer (or winter for southern hemisphere).

In my experience of that cooler (I have a 3700X also) it is rather noisy and the CPU runs hot. Not something I'd want to have running continuously under load.

Yeah, I was asking for theoretical performance. So 14nm+++ really didn't bring a lot of stuff to HEDT.

Okay. You reckon those $70 Noctuas are worth a go? For example their NH-U9DXi4.

Noctua coolers are excellent, I have them on all my crunchers, but you don't want that particular one. It's for the Intel 2011/2066 socket only, so it wouldn't work on an AMD, and the 90mm fan is a bit of a letdown for cooling. Check the socket compatibility list before buying, as some are specific sockets, only, and some have the hardware for many sockets included.

You want the biggest baddest cooler you can afford. For $70, you should be able to get the more powerful U14S which has a 140mm fan (the U12S is almost as good if the case isn't wide enough, U12A is awesome, but much more expensive). For HEDT (2066/TR) the minimum consideration should be the D15 ($80-90), and then save up for watercooling (this is what I'm doing if my 10980xe ever arrives).

PG is quite the heat generator and the more you can cool, the better.

Hmm thanks! In the previous message I meant that would it be too luxurious cooling? Like could I go lower with price (around $50) and get enough (<70C) cooling?
If not, I'll get U14S since I'm not an ITX user and therefore the case is big enough.

Stick with the Noctua, you won't regret the extra few bucks, and the reliability is amazing.

You could go with something cheaper like the Coolermaster Hyper 212 EVO (and even the stock cooler) and achieve those temps, but you wouldn't want to be with the computer in the same room for very long. The cheaper coolers use fans that run loud at half to full speed (and will need to).

Ok, thanks! Noctua has earned a great reputation in Chinese computer enthusiasts here as well.
